Drainage systems: what you need to know about them?

The concept of "drainage system" implies a complex technical structure designed to drain infiltration and groundwater. It also allows you to prevent waterlogging of the soil and, thus, provide favorable conditions for construction and optimal water balance of the soil.

The drainage system usually consists of wells and pipes connected to each other and in one way or another located on the site.
The first drainage systems appeared more than two millennia ago. Then they began to carry out the first reclamation work. The earliest evidence of drainage systems was found in documents written by Herodotus.

The focus is usually on the essential components of drainage systems, such as wells, pumps and pipes. Perhaps you can start the review with pipes.

Until about the last decade of the last century, drainage pipes were made exclusively from asbestos cement or ceramics. Laying such products usually took a lot of time, as it required lengthy preparation. Quite often, ceramic and asbestos-cement pipes clogged, which significantly reduced their service life.

The beginning of the XXI century was marked by the active use of more advanced and reliable technologies, for example, steel electric-welded pipes. Thanks to this technological breakthrough, drainage systems have become more reliable, durable and efficient.

Wells of drainage systems are usually placed where pipes turn. In these places, such structures either set the direction of the flow or act as a catchment. Another purpose of drainage wells is to provide the ability to carry out work related to the maintenance of the system. One such work is flushing pipes.

Pumps solving equally important problems also deserve due attention. For example, with their help, the accumulated water is pumped out, which cannot be removed naturally.

Pumps are usually immersed in wells, since such equipment is designed specifically for working under water. Such devices are represented today by many models that differ in pumping speed.

One of the most important parameters of drainage pumps is the diameter of the nozzle. The higher the indicator of this parameter, the higher the probability of penetration of solid particles into the system.

Installation of a drainage system requires taking into account a number of important factors, for example, ease of installation, the complexity of auxiliary operations, structural features of the system, and some others.

Installation of drainage pipes is usually carried out with a slight slope towards the wells. Thus, water will accumulate in one place from which it will flow into the sewer. Be sure to take into account the distance between the pipes, which is determined by the moisture permeability of the soil and the amount of precipitation.
